The vulnerability has a CVSS score of 6.8 and affects multiple versions of Windows, specifically targeting BitLocker Device Encryption. It requires physical access to the target system, has low attack complexity, and does not require user interaction. The affected Windows platforms include Windows 10 (versions 1607, 21H2, 22H2), Windows 11 (versions 22H2, 23H2, 24H2), and Windows Server editions (2016, 2022, 2025).

Jack Dorsey, co-founder of Twitter, has launched Bitchat, a peer-to-peer messaging app that operates over Bluetooth without the need for internet or phone numbers. Currently in beta testing via Apple's TestFlight, Bitchat uses local Bluetooth mesh networks to relay messages, ensuring encrypted conversations that disappear by default. Users can create password-protected group chats and future updates may include Wi-Fi Direct support. The app is designed for use in situations with compromised internet access and does not collect user data or require accounts. A whitepaper on GitHub outlines its technical framework aimed at resisting censorship. While still in early testing, the app's effectiveness at scale is yet to be evaluated, and there are no announcements for an Android version or public launch plans.

Starting July 7, 2025, Google’s AI chatbot, Gemini, will automatically interact with third-party applications on Android devices, including Messages, WhatsApp, Utilities, and Phone applications. Users can expect Gemini to perform tasks such as sending messages, setting timers, and making phone calls with minimal input. These interactions will occur automatically, regardless of whether the Gemini Apps Activity setting is activated. Conversations will be logged in user accounts for up to 72 hours, even if users disable the Gemini Apps Activity. Google has informed Android users about these changes via email. Concerns regarding privacy have been raised, with Tuta, an encrypted email service, highlighting the lack of transparency from tech companies. Users can disable Gemini's interaction with apps through the Apps settings page or uninstall it entirely using developer tools. Future Android updates may introduce Gemini features to additional devices.

Jack Dorsey has launched a new messaging application called Bitchat, which operates outside the conventional internet framework. Bitchat uses Bluetooth technology to send messages directly between devices, eliminating the need for phone numbers, servers, and data plans. The app allows communication over distances of up to 300 meters by relaying messages through nearby devices. Bitchat does not include usernames, chat backups, or lengthy inbox histories; messages are ephemeral, encrypted, and stored locally. The beta version was launched on Apple’s TestFlight, filling 10,000 testing slots quickly. The app currently supports small group chats with features like hashtags and password protection, and future updates may introduce WiFi Direct support. Bitchat aims to provide direct, unmediated communication, aligning with Dorsey's vision for user-centric technology.

Jack Dorsey, co-founder of Twitter and CEO of Block, has launched a messaging app called Bitchat, which enables communication without internet connectivity using Bluetooth mesh networking. Bitchat operates on a peer-to-peer basis, does not require user accounts, and ensures messages are encrypted and temporary, without interaction with a central server. Users can communicate within a 300-meter radius, and messages can be relayed to others beyond direct Bluetooth range. The app features password-protected group chats, delayed message delivery for offline users, and will support Wi-Fi Direct for improved range and speed. All messages are stored solely on users' devices and are designed to disappear over time. Bitchat is described as a decentralized, peer-to-peer messaging application resilient to network outages and censorship. The beta release quickly filled all 10,000 slots, indicating significant interest.
